Zepto

Zepto exists to solve a narrowly defined problem: people who bill by the minute for online research lose track of time the moment they stop staring at a clock. Rather than asking you to start and stop a timer for every task, the extension runs quietly in the background and streams your Chrome work activity into the companion Zepto-ai dashboard, which turns that raw activity into a clean, reviewable record of the day.

The extension is deliberately lightweight in scope — it is a data-collection bridge, not a full productivity suite. Its job is to observe and pass along what you were working on, so the dashboard can present it as billable time. That separation keeps the browser side simple and puts the reporting and invoicing logic where it belongs, on the dashboard.

Zepto is aimed at researchers, analysts, consultants and anyone whose billable output happens inside a browser. It suits small teams that need defensible, activity-backed timesheets more than they need heavyweight project-management tooling. The listing is a small, long-standing extension (a few dozen active users), so it is best treated as a specialised companion tool rather than a standalone platform.
